Reading on digital screens, especially for complex topics, leads to significantly lower retention and comprehension compared to reading physical texts. This 'screen inferiority effect' is attributed to factors like the lack of tactile cues and the nature of digital interfaces, which can hinder deep processing and long-term memory formation. Studies suggest comprehension can be six to eight times lower on digital media for complex subjects.

Impact: High. This finding challenges the widespread adoption of digital learning tools for in-depth study, suggesting a potential deficit in knowledge acquisition for students relying heavily on screens for academic material.
